McDowell makes low-key return
Graeme McDowell was level par midway through his first round on his return to California for the USPGA Tour AT&T Pebble Beach National Pro-Am.
The Northern Irishman, making his first appearance at the California course since 2010, when he became the first European for 40 years to win the US Open, bogeyed the par-four fourth hole on Spyglass Hill but a birdie at the par-five seventh got him back to even at the turn when the action resumed following a three-hour rain delay.
Daniel Chopra was setting the early pace with a stunning start to his opening round at Monterey Peninsula Country Club.
After teeing off from the 10th, the Swede collected six birdies on his first seven holes to give himself a three-shot cushion over Americans James Hahn, Dustin Johnson, Robert Streb and John Mallinger, and Australia's Stuart Appleby.
American Hunter Mahan, Sweden's Freddie Jacobson, Australia's Jason Day and Scotland's Russell Knox were among a cluster of players on two under midway through their first rounds.
